George’s parents bring a marble rye bread to a dinner party with his fiancé’s parents. When the bread isn’t served, Frank Costanza spitefully steals it back. George has to sneak a replacement rye into the apartment using a fishing pole.
Jerry has to mug an old woman on the street to acquire the specific marble rye George needs. The plan falls apart entirely when the bread is spotted being reeled up the side of the building, destroying any chance of parental harmony.
